Trying to add a simple Date popup

Hello, I try to add a date type popup for my custom power up.

I get the error:

PluginRunner::NotHandled: attempt to run callback on plugin

My code example for the client.js is :

var Promise = TrelloPowerUp.Promise;

var GRAY_ICON = '';

'card-buttons': function (t, options) {
return [{
icon: GRAY_ICON, // don't use a colored icon here
text: 'Start Date',
callback: cardButtonCallback
}, {
appKey: 'your_key_here',
appName: 'My Trello App'

var cardButtonCallback = function (t) {
return t.popup({
type: 'date',
title: 'Start Date',
callback: function(t) {}

Hi Dimitris,

I'd instead recommend posting this over in our developer community:

Our engineers keep an eye out there, and they or any champions would be happy to help you out with this.

I hope that helps point you in the right direction!
